BURNER.

Application led September 3, 1909.

T o all whom it may concern: l

Be it known that I, JOHN Dnucoronszxr a subject of the King of Hungary,residing at Niles, in the county of Trumbull and State of Ohio, haveinvented certain new i and useful Improvements in Burners, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to gas burners and the object of the invention isto provide a l gas burner with a novel auxiliary mixer l adapted tocooperate with the ordinary l mixer in producing a better admixture of las and air.

Another object of the invention is to prol vide a burner with a directinlet pipe to the i mantle, said pipe being independent of the mantle orshade holder'. i

With the above and other objects in view i the invention consists in thenovel construch tion, combination and arrangement of parts to behereinafter described in detail and i then claimed. i

Reference will now be had to the drawing` l forming a part of thisspecification wherein L there is illustrated a preferred embodiment l ofthe invention, but it must be understood that the structural elementsthereof can be varied or changed without departing from l the spirit ofthe invention. 1

In the drawing z-Figure 1 is a side eleva# l tion of the burner partlybroken away and partly in section, Fig. 2 is a plan of a pori tion ofthe same, and Fig. 3 is a vertical sec* tional view of the burner.

Considering the details of construction shown in the drawing, thereference numeral t 1 denotes a gas supply pipe provided with a needlevalve 2 and air inlet casing 3, said i casing having the upper endthereof rei duced, as at 4. These parts are common to the ordinary typeof gas burner and it has i been the policy heretofore t0 mount themantle holder directly upon the reduced end l of the casing 3, but Ihave found that better results can be obtained in the intensity ofalight by interposing an auxiliary air mixer Speccaton of LettersPatent.

between the upper end of the casing 3 and the mantle of the burner. Theauxiliary mixer comprises a pipe 5 mounted in the reduced end 4 of thecasing 3, said pipe adjacent to the fixed end thereof having an annularflange or collar 6 upon which is adapted to rest a sleeve 8 of a lesslength than the pipe 5, said sleeve having the upper end thereof flared,as at 9 and connected to a three pronged spider 10 and a collar 11.Adapted to fit upon the collar 11 is a sleeve 12 of a mantle bracket 13supporting a mantlev 141. The spider 1() is connected to an ornamentalglobe holder 15 adapted to surround the sleeve S and rest upon thecollar 6.

The pipe 5 within the sleeve 8 is provided with av plurality ofapertures 16, and the sleeve S is provided with oblong openings or slots17, these slots when registering with the apertures 16 in the pipe 5admitting additional air to the gas adapted to pass upwardly through thepipe 5 into the mantle 14e. By rotating the sleeve 8 upon the pipe 5,the apertures 16 can be closed by that portion .of the sleeve 8 betweenthe longitudinal edges of the slots 17 Having now described my inventionwhat I claim as new, is

In a gas burner, the combination with a` gas supply pipe, and an airmixer carried thereby, of a pipe connected to said mixer, said pipehaving apertures formed therein, a collar carried by said pipe, a sleevesurrounding said pipe and adapted to be supsaid sleeve having slotsformed therein adapted to register with the apertures of said connectionwith the upper end of said sleeve l and adapted to support a mantle,substantially as and for the purpose herein described.

In testimony whereof I aiiix my signature in the presence of twowitnesses.
